This invention relates to supporting devices and attaching the adapter plate .to the junction box more particularly to a mounting device for an support. f electrical transformer. Referring now to the drawing wherein like An object of the invention is the provision of reference characters designate the same parts 5 an inexpensive and efficient support for electrical throughout the several views, the numeral 11 0 apparatus which be quickly and securely designates a transformer of auvell known type mounted and which may be easily connected to having lugs 12*12 formed on one face thereof and disconnected from its associated electrical by means of which the transformer 11 may be circuit. secured to projecting headed members l3 3.

In accordance with one embodiment of the A supporting device designated generally by the 5 invention, a junction box is provided of a size such numeral 15 forming one embodiment of this inthat it will support an electrical transformer vention includes a junction box 16 having conthrough the cooperation of header members on duits l?-l'7 and 19-19 running thereto and the face thereof the usually provided slotted which electrical conductors i l-14 and l8-13 15 lugs on the rear side of the transformer. One side running to electrical mains (not shown) and to 70.
